Subject: [PATCH 1/4] ARM: OMAP2+: Fix null hwmod for ti-sysc debug
Date: Wed,  8 Aug 2018 01:07:03 -0700	[thread overview]
Message-ID: <20180808080706.100389-2-tony@atomide.com> (raw)
In-Reply-To: <20180808080706.100389-1-tony@atomide.com>

We may call omap_hwmod_parse_module_range() with no hwmod allocated yet
and may have debug enabled. Let's fix this by checking for hwmod before
trying to use it's name.

Fixes: 6c72b3550672 ("ARM: OMAP2+: Parse module IO range from dts for legacy
